  • Austenitic steel matrix-nanoparticle composite and producing method thereof
    Patent number: 10323306
    Abstract: An austenitic steel matrix-nanoparticle composite and a producing method thereof are provided. The composite includes: an austenitic steel matrix that includes an alloying element; and a nanoparticle that grows in situ in the matrix and that is formed in the matrix. The nanoparticle grows from the alloying element included in the austenitic steel matrix. The method includes: preparing an austenitic steel matrix including an alloying element; and heating the austenitic steel matrix. In the method, the nanoparticle grows in situ in the matrix from the alloying element which is solid-dissolved in the austenitic steel matrix by the heating.
